Which of the following are true for gravity? check all that apply. a. gravity is the force that holds objects on the surface of the earth. b. the force of gravity is stronger for objects with more mass. c. as the distance between two objects increases, the force of gravity between them increases. d. gravity is an attractive force, so it pushes all objects apart.

The correct answer to the question is : A) Gravity is the force that holds objects on the surface of the earth and B) The force of gravity is stronger for objects with more mass.

EXPLANATION:

Before coming into any conclusion, first we have to understand the force of gravity.

Gravity is the force with which any body on the surface of earth is attracted towards the centre of earth.

Actually it is the gravitational force which is known as gravity in the context of earth.

The nature of the force is attractive in nature. That's why every body is attracted towards the centre of earth.

The force of gravity experienced by a body on the surface of earth is equal to its weight.

Hence, gravity = mg.

Here, g is known as acceleration due to gravity.

A body having greater mass will feel more gravity as gravity is dependent on the mass of the body.

We know that gravity is the gravitational force. Hence, it will obey inverse square law. Hence, gravitational force decreases with the increase in distance of separation between two bodies.

Hence, the correct answer of this question is option A and B.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
